I remember thinking at the time that the weird thing is that his Nazi costume was supposed to be the Afrikakorps. Which he might have almost gotten away with, as they fought honorably, didn't have any SS units, and have a "cleaner" image than the continental German army- except he wore a red swastika armband, which was not a part of any German army uniform in WWII.

I thought it was weird at the time, and it's still weird when I see the little picture here.
